A confectionary billionaire and a former Ukrainian Prime Minister are going head to head in the country's May elections.
Here in capital Kiev, former Prime Minister Yulia Tymoshenko and confectionary billionaire Petro Poroshenko submit their registrations.
Crimea's been the center of attention following the region's annexation to Russia, raising tensions to the highest they've been between East and West since the Cold War.
Tensions aside, Tymoshenko is calling for unity.
(SOUNDBITE) (Ukrainian) BATKIVSHCHYNA PARTY LEADER AND PRESIDENTIAL CANDIDATE, YULIA TYMOSHENKO, SAYING:
"I think it's high time now in Ukraine to bring order to all spheres of our life. To defend Ukraine from aggressors, to return justice to people - they have been waiting for many years - get rid of corruption and oligarchs in Ukraine and build a strong economy and build a European Ukraine."
While Poroshenko thinks Ukraine needs a new system.
(SOUNDBITE)(English) PRESIDENTIAL CANDIDATE, PETRO POROSHENKO, SAYING:
"We think that the position for supporting Ukraine and introducing the sanctions should be done step by step because we don't have the purpose to make any harm to Russia or to anybody else. We just want to defend Ukrainian territorial integrity, Ukrainian sovereignty. This is point number 1. And point number 2: this is a situation when the old security system - the post war system - is not working."
Poroshenko, also known as the "chocolate king" is worth an estimated $1.3 billion, and is the owner of one of the world's top confectionary firms.
Tymoshenko was released from jail in February after her arch-foe Viktor Yanukovich fled from power.
She was jailed in 2011 for an abuse of office charge.
